Summary Lateral backward masking effect (metacontrast) is studied in a common situation : the perception of a disk is « erased » by a ring ; these two black concentric stimuli are successively presented on a white background of constant luminance. Forty observers use a rating scale for absolute judgments of brightness. The perceived intensity of the lst stimulus is a complex function of the delay between the two stimuli : monotone and U-shaped functions are obtained. The masking stimulus duration is a determining factor : progresswely the U-shaped curve changes into a monotone function when masking stimulus duration increases. proactive effect is also described an inhibition is followed by facilitation These data are compared with results f...
